A
The chipper-shredder is designed for two different
methods of operation.
• Leaves and small branches up to 1/2" diameter
(recommended) or 1" diameter (maximum) can be
fed into the hopper assembly. See figure 5. If it
becomes necessary to push material into the chip
per-shredder, use a small diameter stick—NOT
YOUR HANDS. The stick should be small enough
that it will be ground up if gets into the impeller
assembly.

IMPORTANT: There is a flail screen located inside
the housing in the discharge area. If the flail screen
becomes clogged, remove and clean as instructed in
the Service and Adjustments section. For best per
formance, it is important to keep the shredding blade
and the chipper blades sharp. If the composition of
the material being discharged changes (becomes
stringy, etc.) or if the rate at which the material is dis
charged slows down considerably, it is likely that the
shredding blade and/or chipper blades are dull and
need to be sharpened or replaced. Refer to Service
and Adjustments section.
